Multi-scale cortical keypoint representation for attention and object detection

Keypoints (junctions) provide important information for focus-of-attention (FoA) and object categorization/recognition. In this paper we analyze the multi-scale keypoint representation, obtained by applying a linear and quasi-continuous scaling to an optimized model of cortical end-stopped cells, in order to study its importance and possibilities for developing a visual, cortical architecture.We show that keypoints, especially those which are stable over larger scale intervals, can provide a hierarchically structured saliency map for FoA and object recognition. In addition, the application of non-classical receptive field inhibition to keypoint detection allows to distinguish contour keypoints from texture (surface) keypoints.

Multi-scale keypoint hierarchy for Focus-of-Attention and object detection

Hypercolumns in area V1 contain frequency- and orientation-selective simple and complex cells for line (bar) and edge coding, plus end-stopped cells for key- point (vertex) detection. A single-scale (single-frequency) mathematical model of single and double end-stopped cells on the basis of Gabor filter responses was developed by Heitger et al. (1992 Vision Research 32 963-981). We developed an improved model by stabilising keypoint detection over neighbouring micro- scales.

Crieff Hydro Hotel: the experience economy and the guest perspective

The purpose of this report is to do a presentation of the hotel where I will be working, characterising the reception department and all the activities that I developed during this placement. On this placement at the CHH (Crieff Hydro Hotel) – family 4 stars resort, my goal is to have an experience in hospitality, in special in reception. This placement is carried out from my Master degree in Direcção e Gestão Hoteleira (Commercial branch) at the University of the Algarve – Campus Penha. For this report it was also intended to do an analysis of the guest experience in hospitality and for that it was necessary to do a literature review adequate for my area of work in the hotel giving importance to the guest experience in the hospitality. For my analysis regarding the guest experience in hospitality, I used data collected from the surveys answered by the guests that stayed with us in the hotel. To analyse the data it was necessary to do a categorial analysis technique. After this year of placement in the hotel and after this analysis, as results I have the opportunity to continue my work in the hotel and also the possibility of a better position in a near future. Last but not least, this report demonstrates my work path and also helps to have a better understanding of the satisfaction perceived by the guest in order to give us tools to improve it. From what we can see, the guests’ satisfaction is highly rated on both surveys.
